HOW TO STORE YOUR JACK

This jack is designed for compact and convenient storage (see Fig. 5).

• Insert the rubber handle holder onto the top nut.

• Depress the spring lock to separate the handle pieces, and insert them into the handle

holder.

MAINTAINING OIL LEVEL

Important: When adding or replacing oil,
ALWAYS use a good grade Hydraulic Jack
oil. DO NOT use Hydraulic Brake Fluid,
Alcohol. Glycerine, Detergent, Motor Oil or
dirty oil. Use of an improper fluid can cause
serious internal damage to your jack.

ADDING OIL

• Position the jack on level ground in an

upright (vertical) position and fully lower the
saddle.

• Remove oil filler plug (see Fig. 3).

• Oil should be filled to the level of the oil

filler plug hole. If low, add oil as needed.

REPLACING OIL

• To drain oil, remove oil filler plug and open

release valve (see Fig. 3).

• Turn jack on its side and drain old oil out

through the oil filler plug hole.

• Refill with new oil through the oil filler plug

hole. DO NOT allow dirt or other foreign
material to enter the hydraulic system when
filling.

• After refilling, remove any air from the

hydraulic system by opening the release
valve and rapidly pumping the jack handle
several times.

• Replace the oil filler plug.

LUBRICATION

• Add lubricating oil to all moving parts as

needed.

PREVENTING RUST

• Check ram and pump plunger (see Fig. 3)

every few months for any signs of rust or
corrosion. Clean as needed by wiping with
an oily cloth.

• When not in use, ALWAYS store jack with

saddle and pump plunger lowered all the
way down.
